Why was there a boom in the United States of America in the 1920's

The most important reason for the boom was, in my opinion, the First World War. It gave Americans and their industry a flying start in the 1920's. The industries grew during the war and were geared up, ready to meet with the enormous demand for United States goods after the war effort in the different countries, had ended.

Other important factors that helped bring the boom were, a lot of confidence among Americans willing to invest in new products and ideas, and take risks with their money. This meant that businesspeople bought shares in industry etc.

Factors which contributed to the boom were, their was lots of credit that allowed many more American citizens to buy goods even if they did not have the money to pay straight immediately. Also, natural resources such as raw materials, were in large stores, ready to be used when new products needed to be produced, such as cars.

The factors linked because of a chain reaction. More credit meant the means to purchase goods, goods were able to be made because of the large store of natural resources and things could be made and produced because the money was their, supplied by the confident American people. All of the individual things helped to cause the boom, if one link was missing then boom would have more than likely not occurred.
